Question

How can you tell which one is the red light or the UV region light?

**Instruction:**

Assume that one of the following transitions gives red light and the other gives light in the UV region. *Label* the appropriate picture with the appropriate "kind" of light and *explain* how you inferred your answer.

**Diagram Description:**

- The images show two diagrams of electron transitions in atoms.
- Each diagram depicts a nucleus at the center with three concentric circles representing energy levels around the nucleus.
- An arrow indicates the direction of the electron transition from a higher to a lower energy level.

---

**Explanation:**

When an electron transitions from a higher energy level to a lower energy level, it emits a photon. The energy difference between the two levels determines the wavelength of the emitted light. 

- **Red Light Transition**: This occurs when the energy difference is smaller, as red light has a longer wavelength and lower energy. Therefore, the transition depicted with a smaller difference in energy levels should be labeled as producing red light.
  
- **UV Light Transition**: This occurs with a larger energy difference, as UV light has a shorter wavelength and higher energy. The transition with a larger difference in energy levels should be labeled as producing UV light.
